Electrical Parameters
As detailed in the KEMET Surface Mount Catalog F3102 for X7R,with the following specific requirements based on room temperature (25°C) parameters:
· Operating Range: -55°C to +125°C, with no-bias capacitance shift limited to the ± 15% over that range.
· Insulating Resistance (IR) measured after 2 minutes at rated voltage @25°C: Limit is 500 megohm microfarads or 10,000MW, whichever of the two is smaller.
· Capacitance and Dissipation Factor (DF) are measured under the following conditions:
   1kHz and 1 Vrms if capacitance * 10µF
   120Hz and 0.5 Vrms if capacitance $ 10µF
· DF limits:
   50 -200 Volts ü 2.5%
   16 -25 Volts ü 3.5%
   6.3 / 10 Volts ü 5.0%
  
Soldering Process
All parts incorporate the standard KEMET barrier layer of pure nickel, with an overplate of pure tin to provide excellent solderability as well as resistance to leaching. The recommended mounting techniques are as follows:
· 0402 / 1210 case sizes ü Solder Reflow
· 0603 / 0805 / 1206 case sizes ü Solder Wave / Solder Reflow
